[Qemu-ppc] [PATCH v2 0/3] Enable MTTCG on PPC64

[Nikunj A Dadhania]

The series enables Multi-Threaded TCG on PPC64

Patch 01: Use atomic_cmpxchg in store conditional
      02: Handle first write to page during atomic operation
      03: Generate memory barriers for sync/isync and load/store conditional

Patches are based on ppc-for-2.10

Changelog:
v1:
* Rewrote store_conditional as suggested by Richard

Tested using following:
./ppc64-softmmu/qemu-system-ppc64 -cpu POWER8 -vga none -nographic -machine 
pseries,usb=off -m 2G  -smp 8,cores=8,threads=1 -accel tcg,thread=multi  f23.img

Todo:
* Implement lqarx and stqcx
* Enable other machine types and PPC32.
* More testing for corner cases.
